The SR 836/NW 87th Avenue Interchange Westbound Flyover improvements are nearing completion with the on ramp from northbound NW 87th Avenue to westbound SR 836 now open to traffic. This project strives to address system-to-system connections between SR 836 and the Palmetto Expressway and provide increased capacity to meet future traffic needs along SR 836. It encompasses eastbound and westbound SR 836 from just east of NW 97th Avenue to just west of NW 82nd Avenue. It also extends along NW 12th Street from just west of NW 87th Avenue to just east of NW 82nd Avenue; and on NW 87th Avenue from just south of the SR 836 overpass to north of NW 12th Street.
BPA provided roadway, structural and construction support services under a Construction Savings Initiative (CSI) contract for this redesign and reconstruction, which significantly improves congestion and traffic flow at the SR 836/Dolphin Expressway interchange with NW 87th Avenue by providing new direct expressway access. Our design scope included bridge, roadway approaches, retaining walls, lighting system, signalization and S&PM.
BPA redesigned the project’s Bridge No. 7 Structural Steel Box Girder; a 271 ft. single-lane bridge and the longest curved simple-span dual steel box girder structure in the State of Florida. The original design comprised a 483 ft. long two-span curved continuous plate girder bridge structure. BPA performed a slight realignment of the bridge and modified the structural system using steel box girders saving the project approximately 42%, or 539,000 pounds, of steel. BPA was also the Roadway Engineer of Record for a CSI for the re-design of Ramp D3 (Bridge No. 7), which provides access from NW 12th Street to westbound SR 836.
